New ICS IF SAW Bandpass Filters Match 3G Protocols; Expanded SAW Filter Portfolio Ideal for WCDMA, CDMA2000, and TD-SCDMA 1-, 2-

Integrated Circuit Systems, Inc. (ICS)(NASDAQ:ICST), a
world leader in silicon timing solutions for the consumer, networking,
and industrial electronics industries, today announced availability of
seven new high-performance surface acoustic wave (SAW) products ideal
for use as intermediate-frequency (IF) filters for all
third-generation (3G) base station equipment protocols. The addition
of these devices expands the ICS standard portfolio to 17 SAW filters
for 3G infrastructure applications.
   ICS now offers a wide range of standard 70- to 350-MHz IF SAW
bandpass filters to meet the most stringent performance requirements
of 3G infrastructure protocols, including WCDMA/UMTS, CDMA2000, and
TD-SCDMA. The ICS filters are available in a variety of bandwidths to
match the requirements for single-, two-, and three-carrier systems.
   Proprietary ICS software and modeling technology allows the
filters to be designed for excellent selectivity while maintaining
relatively low loss and extremely flat passband with very low group
delay ripple. This provides base station designers with high-end
filters that are critical to achieving maximum system performance. For
example, the SF0140BA03107S, designed for a two-carrier system, is
centered at 140 MHz and has a 10 MHz bandwidth. This filter offers an
excellent 35-dB rejection bandwidth of 14 MHz, a low insertion loss of
8 dB, and an ultra-low amplitude ripple of 0.25 dB.
   The standard product offering centered at 140 MHz has been
expanded to cover nearly any bandwidth required for base station
amplifiers, repeaters, and transceivers. ICS has also added new parts
at 240 and 350 MHz to provide IF filters suitable for higher-frequency
2-GHz systems. SAW filters for single-carrier 3G-CDMA systems are now
available at 69.99, 141, 240, and 350 MHz. Further customization
capability is available within this range to provide the exact center
frequency required by a base station provider's frequency plan.
   The new ICS SAW devices are lead-free and RoHS-compliant, offering
designers a highly reliable, consistent, and cost-effective method of
filtering IF signals in 3G base station applications. In addition to
standard products, ICS also offers custom-designed SAW filters to meet
unique system requirements.

   Pricing and Availability

   All 17 standard SAW filters for 3G base station applications are
in production and available now. Pricing starts at $15 in 1,000-piece
quantities for the SAW filters in SMP1306 (13.3 x 6.5 mm) packages.
